Please Note: This pallet contains 48 x 20kg bags of ARDEX X77 Grey. Always refer to the manufacturer’s latest technical data sheet for substrate preparation, mixing instructions, application requirements and curing times.
ARDEX X 77 is perfect for installing ceramic, fully vitrified tiles, and other low-porosity tiles like glass mosaics, porcelain mosaics, and terrazzo. The adhesive is certified under BS EN 12004 with a C2 TE S1 classification, meaning it offers improved performance, reduced tile slip, and extended working time. ARDEX X 77 and ARDEX X 77 W provide up to 60 minutes of open time—twice the industry requirement—and have double the slump resistance compared to standard adhesives. These qualities make them ideal for both indoor and outdoor tile installations, including challenging environments like swimming pools.
Surface Preparation: Before tiling, ensure surfaces are clean, solid, and free of dust, grease, or anything that might prevent proper adhesion. The surface must be strong enough to support the tile weight and properly dried according to BS 5385 standards. Prime the surface if needed before tiling. For ceramic tiles, the surface should be even, with no more than a 3mm gap under a 2m straight edge (Surface Regularity 1). ARDEX X 77 can be used on both dry and slightly moist surfaces, but moisture-sensitive materials must remain dry. In wet areas, use the ARDEX WPC Waterproof Protection System to safeguard against water damage.
Mixing: Mix ARDEX X 77 or ARDEX X 77 W powder with clean water in a clean container. Use a mixing paddle attached to a variable-speed electric drill for best results. The ratio is about 2 parts powder to 1 part water. A 20kg bag needs around 8.5 litres of water. Don’t exceed the maximum water amount. Adjust the consistency for your specific needs. Mix and apply the adhesive at temperatures above 5°C, and note that the mixed mortar has a pot life of approximately 3 hours at 20°C.
Application: Use a trowel to apply the mixed adhesive to the surface, then comb it with a notched trowel to create a ribbed bed. Press tiles into place within the adhesive’s 60-minute open time, using a twisting or sliding motion for good contact. For wall tiles in dry areas, ensure at least 50% of the tile’s back is covered in adhesive; for best results, aim for 80% coverage. For floors, wet areas, or external locations, butter the back of the tiles before placing them to eliminate voids. Choose the notched trowel size based on the tile size, surface, and desired coverage.
Grouting: Grout once the adhesive has hardened enough that tiles won’t move. Wall tiles are usually ready for grouting after 8 hours at 20°C, and floor tiles after 24 hours, depending on tile porosity and surface type. Adjust grouting times if temperatures are higher or lower. Use ARDEX-FLEX Tile Grout for most applications, or ARDEX EG 8 Cement/Epoxy Hybrid Grout for areas requiring chemical resistance and hygienic joints, like commercial kitchens.
